Mirvac celebrated the start of construction at its latest Premium-Grade office building in Melbourne, Olderfleet at 477 Collins Street, with a sod turning event on site. Olderfleet will be one of Mirvac’s largest commercial developments in Australia once complete and is on track to be delivered in 2020, with demolition and concrete piling already well underway.

The 40-storey office tower is designed by Grimshaw Architects, rising from the unique 1880s facades of the heritage buildings along Collins Street. Deloitte will be the anchor tenant for the building, taking 22,000 square metres of office space for 12 years starting in June 2020. There is 30,000 square metres of lettable premium office space across 18 floors remaining, with strong interest from a number of prospective tenants.

Grimshaw’s design incorporates a vertical village concept where the tower has been split into three separate modules to express key internal workings of the building and make strong connections with the heritage context. Deloitte has committed to the middle village within the tower, leaving the top and lower villages available. The top village, or sky rise, will have stunning views of the Melbourne CBD, with a rooftop terrace perfect for entertaining.

The building uses large floor plates for flexibility with doors to the terrace looking onto spacious outdoor spaces. This design allows for outdoor terraces on each village, a rare advantage for an office building in Melbourne. Deloitte’s terrace wraps 270 degrees around the top floor of their village, making it the perfect place for meetings and their reception area.

The building will have one of the largest office lobbies in Melbourne with a 30-metre-high glass atrium connecting the heritage buildings to the new office tower, providing a unique view of the heritage façade. This space will include a lobby café and a flexible business centre with meeting rooms on the lower ground floor. The office tower will rise from the heritage buildings, which will remain intact with an extensive refurbishment and modernisation of the interiors to create boutique office and retail space.

These buildings were built between 1887 and 1889 and were designed by a number of architects resulting in varying Gothic and Romanesque Victorian architecture. Olderfleet is committed to a 5 Star Green Star rating, a 5 Star NABERS energy rating and is a targeting Platinum WELL certification. Source and images, Courtesy of Grimshaw Architects.
